Siemens xEffect Miniature Circuit Breaker 1-Pole 32A Type B 240V AC 48V DC 10 kA Breaking Capacity 278538 FAZ-B32/1

Eaton 278538 FAZ-B32/1 Miniature Circuit Breaker is engineered for efficient and safe circuit protection in industrial, commercial, and residential electrical installations. This 1-pole MCB is rated for 32 amperes and designed to operate at 240V AC and 48V DC supplies, offering versatile application across different power systems.

The device employs a Type B tripping characteristic with a thermal magnetic release to rapidly disconnect circuits experiencing faults at three to five times the rated current, protecting equipment from overload and short circuit damage. Its high selectivity rating is essential for minimizing unnecessary system downtime caused by upstream tripping. Rated with an IP20 touch protection standard, the breaker is safe to use in environments where protection from operator contact and solid foreign objects is required.

The robust construction ensures the MCB withstands mechanical shocks typical in industrial settings and guarantees durability over more than 10,000 operation cycles. Installation is straightforward, clipping securely onto a standard 35mm DIN rail, with the option of hand-tightened screw mounting thanks to its low mounting torque. The 10 kA breaking capacity makes it suitable for many heavy-duty applications where high fault levels may occur. A 4kV impulse withstand voltage rating further protects electrical systems from transient voltage spikes.

Typical use cases include industrial manufacturing plants, commercial electrical boards, automation control cabinets, and any electrical distribution system requiring reliable overcurrent protection.

High selectivity reduces unnecessary downtime caused by upstream trips. Thermal magnetic tripping mechanism ensures fast response to overloads and short circuits. Shock-resistant construction suitable near moving machinery.

IP20 touch protection rating complies with electrical safety standards. Durability exceeds 10,000 mechanical operation cycles. Simple snap-on installation on DIN rails with optional screw fixing. 10 kA breaking capacity supports heavy industrial applications.

Impulse withstand voltage of 4kV provides robust surge protection.
